I didn’t pass judgment on whether Damian Hockney should stand down from the London Assembly when I wrote about his defection. However, UKIPwatch relays a good case, if true, for him to stand aside:

A UKIP spokesman said that in 2003, Mr Hockney had proposed a motion, passed by the party’s National Executive Committee, requiring any successful UKIP election candidate who later left the party to resign their seat.

‘UKIP asserts that Mr Hockney has a moral obligation, if not a legal one, to adhere to a rule which he himself was a vocal advocate of,’ said the spokesman.
